    Solar module recycling is unprofitable today. In this paper potential revenues from waste Si modules are analyzed. The biggest revenue potential comes from the Si cells, extracted intact or broken. The second revenue source is the bulky materials in the modules including Al frame, Cu wiring and glass. The total revenue is estimated between US$11–30/module depending on the percentage of cells extracted intact. This revenue is 4–10 times better than today’s recycling process that recovers only the bulky materials. Experimentally a special furnace has been demonstrated to successfully separate thin commercial Si cells of 160 microns from glass unbroken. From damaged cells a new chemistry has been developed to recover solar-grade Si and Ag. It requires fewer steps than today’s recycling process, with Ag recovery of 97% and Si recovery of 90%. A prototype recycling line is needed to assess the cost of the new process.
